Applications of Data Engineering

Image
In a previous blog post about data engineering, we went through several many concepts related to data engineering such as data modeling, and then we went through different types of databases, for example, relational databases and we also got a glimpse of relational as well as NoSQL databases. And in today's blog post we will be writing about data engineer applications. Which are basically the use cases of data engineering 1st let's see what data engineering applications mean; so basically when we have data and we have engineered it then there are several things that we can do with that data and these things that we can do with processed data are the use cases of the data engineering. For example: If we have filled our containers with the data then it's not of any good use if it is not clean and well-formed. If your data is well-formed and if there are no logical mistakes, missing values, and garbage then we can easily perform the use cases and applications of data enginee...

PHP chess board : how to make ?

As we have learned much of the basics of  HTML and CSS . Let us now learn how can we make our web applications more user friendly, flexible and versatile, using php . Today we will see how to make a chess board using php in collaboration with HTML and CSS .  So, Let's start: BASIC php SYNTAX: Starting Closing Tags: <?php ?> Php code must be written in these tags. Variables:              Start with "$" sign e.g. $num=3;               ; is really important to put after every statement. Functions:              Functions start with the keyword "function". E.g. function power(){} Print:             echo "printing by using echo";             echo ("printing by using echo");             print "pri...

Good Pieces of Advice for Freshers

To let you know a few useful things, I asked some experienced people, and here is what they have for you... Be open to changes. Focus on improving your soft / people skills. It will be hard sometimes but believe in yourself. You have got it. ( Rahat-Undergraduate ) Try to do good in quizzes and OHTs (One hour test or mids) cause when finals don't go well, these can help in getting good gpa which are comparatively easy then finals. ( Ayesha Munir-Undergraduate )   A few years later when you would look back at this time, GPA won't make you happy, but the memories of these 4 years will. Your career is important but so is having a good time. So work hard, party harder! ( Haris-Undergraduate ) From the start try to build your connections with seniors because they know more than you and.. are best counselors.. Focus on your quizzes and assignments because they are the building blocks of your Grade.. Your Good Image play some important part for favoritism points in exam....

Relational Data Model

-
Image
In the previous blog post, we covered Data Modeling. We have seen that data modeling is really important before jumping into predictive modeling.  In this article, we will cover the Relational Data Model (RDM). Let's start from the very basics, relational means anything which is linked with some other thing. This link is called "Relationship". In RDM or RM there are major three types of relationship cardinalities (also called Multiplicities or Cardianalities): 1. One to one 2. One to many 3. Many to many We can understand these with the help of a few simple examples;  One to one: One department has one manager. One to many: One class has many students. Many to many: Many teachers can teach many students. Okay, so we have got an abstract overview of the term " Relational ", now the next thing is " Data ", data covers everything, anything... And finally, " Model " means something in the form of a template, design, a kind of blueprint.  To store...

NoSQL database

-

  Data is everywhere, it is expanding with each passing day. Relational Database systems are kind of fixed and static. When we have something in abundance and without any standard formation, then the tables of relational database systems cry out.  So what to do with so many data integrations from several structured as well as unstructured sources. Well, the answer is to go for NoSQL (Not Only SQL). SQL is a structured query language that is used to query Relational Databases. However, NoSQL database does not contain data in the form of relations. Most of the NoSQL databases follow the JSON type structure to store data.    Formal Definition:      Guru99  provides a pretty nice definition for NoSQL databases: " NoSQL Database  is a non-relational Data Management System, that does not require a fixed schema. It avoids joins and is easy to scale. The major purpose of using a NoSQL database is for distributed data stores with humongous data stora...

Data Science : The Fusion Reaction

“ Data is the new oil? No: Data is the new soil. ”          ~ David McCandless These days plethora of new things are coming like: "Naya Pakistan" , "Naya prime-minister" , "Naya Semester" and the list goes on... but Let's just talk about this "new soil" science that is "Data Science " Data Science is made up of two words: Data and Science.  Data is a Latin word and a plural of  datum, meaning "thing" It is first used in English in 1640's (17th Century ).  Science came from Latin too, it is derived from a Latin word "scientia" meaning knowledge . Then the old French said : "Hey, I don't like "scientia" let's call it "escience" or just forget about "e" in the beginning and say it: "science" " . Then an English came and said : "I order you to take this word as "science" and no more debate on this !" ...

PintOS : Series : Part 2

-
Image
I hope you have installed PintOS . Now it's time to move forward... In the first assignment we need to check and pass first six test cases of alarm. These are as under: alarm-single alarm-multiple alarm-simultaneous alarm-priority alarm-negative alarm-zero You will find them in " /tests/threads " directory. You need to make changes to " timer_sleep() " function in " timer.c " file under " devices " directory, to pass these tests. But first you should start learning from : here also I have a paper :  here After reading and understanding the reading material, you will be able to start coding! (exceptional cases are always there...) I also need to read it first, so I will let you know more later (after understanding it fully..) So, let's jump right into it (I mean let's start reading!)

I Just want to write code !

-

John Z. Sonmez explains in his book :  "Soft Skills: The Software Developer's Life Manual"  that the attitude of leave me alone, I just want to write code ! Won't work in the life of software developers. Because like other fields, software developer needs to deal with people more than with the computer.So, software developers must work on their soft skills/ people skills. If the software developer is writing code, in that case too, he/ she is writing code for people. The software developer first consider the people's requirements for the product. Otherwise the product is of no use.  So, do you agree with John Z. Sonmez  ? write about it in the comment box !
